i just received my lephone last week and think that they already modified it. but would really like to know what i must do now to change the os. newbie here dont realy know! but one problem ive notice. the gprs and wireless network cannot work together. when i switch on the gprs/3g, the battery goes down quickly and when i turn if off i must restart the phone to turn it on because without restarting the phone, it does not indicate the 3g. dou you think that its a hardware problem or software.. 2- I looses network very often even with the metal back cover. any solution. please friend.
